Is it permissible to link the savings amount, which cannot be received until the age of sixty, to gold or any other currency?

The savings scheme, where a portion of an employee's salary is deducted and a portion is added by the employer, is permissible if the employee's permission is obtained. Investing these funds is also permissible if the investment and transactions are lawful.

However, if the investment is in prohibited matters such as usury (riba) or gambling, then it is not permissible to participate unless it is obligatory and the person finds no alternative. In such a case, it is not permissible for him to take the usurious profits; rather, he must spend them on charitable causes.

It is forbidden to link savings funds to gold or another currency because that constitutes selling a currency for a currency or gold for a currency without immediate mutual possession (qabdh), which is a condition for selling gold and currencies.
